Capturing mobile underwater pseudonoise synchronous signal using multi‐strategy in waveform domain
Electronics Letters, 2023 Capturing pseudonoise (PN) synchronous signals is an important issue in spreading spectrum underwater acoustic communication. In this letter, local waveform domain information is combined with multi‐strategy to enhance the Doppler tolerance of ...

Simulation of a submarine to submarine QKD system [PDF]
Quantum Information Science and Technology IV, 2018 Due to the absorption of water, communication between two parties submersed below the water is normally performed with acoustic waves. However, with the need for higher data rates, the use of RF or optical frequencies is needed. Currently optical wavelengths have been demonstrated for classical communication over short distances.

Computational Investigation of Seakeeping Performance of a Surfaced Submarine in Regular Waves
한국해양공학회지, 2022 A submarine is optimized to operate below the water surface because it spends most of its time in a submerged condition. However, the performance in free surface conditions is also important because it is unavoidable for port departure and arrival ...
